Abstract

Students show deficient understanding on fraction division and supporting that understanding remains a challenge for mathematics educators. This article aims to describe primary students’ understanding of partitive fraction division (PFD) and explore ways to support their understanding through the use of sequenced fractions and context-related graphical representations. In a design-research study, forty-four primary students were involved in three cycles of teaching experiments. Students’ works, transcript of recorded classroom discussion, and field notes were retrospectively analyzed to examine the hypothetical learning trajectories. There are three main findings drawn from the teaching experiments. Firstly, context of the tasks, the context-related graphical representations, and the sequence of fractions used do support students’ understanding of PFD. Secondly, the understanding of non-unit rate problems did not support the students’ understanding of unit rate problems. Lastly, the students were incapable of determining symbolic representations from unit rate problems and linking the problems to fraction division problems. The last two results imply to rethink unit rate as part of a partitive division with fractions. Drawing upon the findings, four alternative ways are offered to support students’ understanding of PFD, i.e., the lesson could be starting from partitive whole number division to develop the notion of fair-sharing, strengthening the concept of unit in fraction and partitioning, choosing specific contexts with more relation to the graphical representations, and sequencing the fractions used, from a simple to advanced form.

Abstract

The service of recording and borrowing goods at the Teacher Learning Center agency is currently still being carried out manually. parties who will borrow goods must come to the teacher learning center directly and record borrowing data and item data is still done manually, whereas at this time it has entered the era of the industrial revolution 4.0, of course, everything will have efficiency and very fast access. With this problem, of course, the right solution is to have a system that can borrow and record goods based on a website. The process of creating and designing a website uses the Rapid Application Development model, which is a method that starts with the requirements planning stage, RAD design workshop (work with users, build system) and implementation. Testing on the application uses alpha and beta testing, alpha testing uses blackbox testing while for beta testing uses the mean opinion score (MOS). Alpha testing obtained the website running according to what was expected to be successful while beta testing obtained a measurement result score with 10 respondents, namely 88.60% based on alpha testing and beta testing, it was concluded that this website was able to meet and support the needs of users and agencies.

Abstract

The development of information technology has encouraged organizations to improve information management. However, the Association of Indonesian Academics and Scientists (ASASI) West Nusa Tenggara does not yet have an integrated web-based system for managing and presenting management member profiles. As a result, profile information is scattered, lacks structure, and is difficult for both internal members and the public to access. Additionally, management members have limited ability to independently manage and update their profile data. This study aims to design and implement an HTML-based frontend for a management member profiling system that enables both visualization and self-management of profile data. The system is developed using HTML, CSS, and PHP native without frontend frameworks or RESTful APIs to ensure simplicity, ease of maintenance, and suitability to organizational needs. The effectiveness of this approach is evaluated using usability, accessibility, and maintainability indicators, including ease of navigation, clarity of information presentation, and minimal dependency on external frameworks. The results show that the system successfully provides structured and user-friendly profile information while enabling efficient data management by users. The system improves transparency, enhances information dissemination, and supports more effective organizational management in the digital era.

Abstract

The badminton court booking system in East Lombok still operates manually, requiring customers to visit the location in person. Based on observations, this manual method serves 10–15 customers per day, but only a portion can be confirmed properly. This is due to the use of manual methods that often cause problems such as errors in recording reservations, lost reservation data, and clashing reservation schedules. To overcome these problems, this study aims to design a web-based badminton court booking system to simplify and expedite the booking process. The system development uses the waterfall method, which includes the stages of analysis, design, implementation, testing, and maintenance. The result of this study is a web-based badminton court booking system that is able to process online reservations, display available schedules in real time, and minimize recording errors. Testing using black box testing and User Acceptance Testing (UAT) shows the system runs well, with a user acceptance rate of 86.4% based on responses from 15 respondents. This system improves efficiency and accuracy in the booking process.

Abstract

Extracurricular management at MAN 1 Lombok Timur currently faces administrative challenges, where 64.7% of attendance and reporting processes are still conducted manually based on survey. This manual system leads to high risks of data loss and inefficiency in monitoring activities. This research aims to design and develop a web-based extracurricular information system using the Personal Extreme Programming (PXP) method to improve administrative efficiency. The PXP methodology consists of requirements, planning, iteration, design, implementation, and testing phases. The developed system integrates key features including digital attendance, gallery management, and automated reporting. Testing was performed using Black Box Testing and User Acceptance Testing (UAT). The results of Black Box testing, covering both positive and negative scenarios, demonstrate that the system is robust and functions according to the requirements. UAT results indicate high user acceptance, suggesting that the system successfully provides a transparent and structured platform for supervisors, administrators, and members. Based on both blackbox and UAT results, this system can replace manual processes in extracurricular management.
